WARNING:
When using electric
gardening appliances, basic safety
precautions must always be followed
to reduce the risk of fire, electric shock,
and serious injury. Read and follow all
instructions.
,_ WARNING:
Always disconnect
unit from power source when making
repairs, adjustments, and when changing accessories and attachments such
as saw bar, chain or guards.
Because a chain saw is a high-speed
woodcutting tool, special precautions
must be observed to reduce risk of accidents. Careless or improper use of this
tool can cause serious injury.

cord. Make sure your extension cord
is in good condition. Inspect extension
cord before use and replace if damaged. Do not use a damaged cord.
Cord insulation must be intact with no
cracks or deterioration. Plug connectors must be undamaged. An undersized extension cord will cause a drop
in line voltage resulting in loss of power and overheating. If in doubt, use the
next heavier gauge. The lower the
gauge number, the heavier the cord
(see SELECT AN EXTENSION CORD in
the OPERATION section). Do not use
multiple cords.
Do not abuse cord. Never carry the
unit by the extension cord or yank
extension cord to disconnect unit.
Secure extension cord to power cord
to prevent disconnection from unit.
Do not use the unit if the switch does
not turn the unit on and off properly,
or if the lock-out does not work. Repairs to the switch must be made by
a Sears Service Center.
Keep extension cord clear of operator and obstacles at all times. Position cord so that it will not be caught
on branches. Do not expose cords to
heat, oil, water, or sharp edges.
To avoid the possibility of electric
shock, avoid body contact with any
grounded conductor, such as metal
fences or pipes.

all.WARNING:
Avoid kickback which
can result in serious injury. Kickback
is the backward, upward or sudden forward motion of the guide bar occurring
when the saw chain near the upper tip
of the guide bar contacts any object
such as a log or branch, or when the
wood closes in and pinches the saw
chain in the cut. Contacting a foreign
object in the wood can also result in
loss of chain saw control.
• Rotational
Kickback can occur
when the moving chain contacts an
object at the upper tip of the guide
bar. This contact can cause the
chain to dig into the object, which
stops the chain for an instant. The
result is a lightning fast, reverse
reaction which kicks the guide bar up
and back toward the operator.
• Pinch-Kickback
can occur when the
the wood closes in and pinches the
moving saw chain in the cut along
the top of the guide bar and the saw
chain is suddenly stopped. This sudden stopping of the chain results in a
reversal of the chain force used to
cut wood and causes the saw to
move in the opposite direction of the
chain rotation. The saw is driven
straight back toward the operator.

SAFETY
FEATURES
,_ WARNING:
The following features are included on your saw to help
reduce hazard of kickback; however,
such features will not totally eliminate
this danger. Do not rely only on safety
devices. Follow all safety rules to help
avoid kickback and other forces which
can result in serious injury.
• Hand Guard: designed to reduce the
chance of your left hand contacting
the chain if your hand slips offthe
front handlebar.
• Position of front and rear handlebars:
designed with distance between
handles and "in-line" with each other.
The spread and "in-line" position of
the hands provided by this design
work together to give balance and
resistance in controlling the pivot of
the saw back toward the operator if
kickback occurs.
• Reduced-Kickback
Guide Bar: designed with a small radius tip which
reduces the size of the kickback
danger zone on the bar tip. This type
bar has been demonstrated to significantly reduce the number and seriousness of kickbacks when tested in
accordance with ANSI B175.1.

SAFETY NOTICE: Exposure to vibrations through prolonged use of hand
tools could cause blood vessel or
nerve damage in the fingers, hands,
and joints of people prone to circulation disorders or abnormal swelling.
Prolonged use in cold weather has
been linked to blood vessel damage in
otherwise healthy people. If symptoms
occur such as numbness, pain, loss of
strength, change in skin color or texture, or loss of feeling in the fingers,
hands, or joints, discontinue the use of
this tool and seek medical attention.
An anti-vibration system does not
guarantee the avoidance of these
problems. Users who operate power
tools on a continual and regular basis
must closely monitor their physical
condition and the condition of this tool.
DOUBLE INSULATION
CONSTRUCTION
This unit is double insulated to help protect against electric shock. Double insulation construction consists of two
separate "layers" of electrical insulation
instead of grounding.
Tools and appliances built with this insulation system are not intended to be
grounded. No grounding means is provided on this unit, nor should a means
of grounding be added to this unit. As a
result, the extension cord used with this
unit can be plugged into any polarized
120 volt electrical outlet.
Safety precautions must be observed
when operating any electrical tool. The
double insulation system only provides
added protection against injury resulting
from an internal electrical insulation
failure.
WARNING:
All electrical
repairs
to this unit, including housing, switch,
motor, etc., must be diagnosed and repaired by qualified service personnel.
Replacement parts for a double insulated appliance must be identical to the
parts they replace. A double insulated
appliance is marked with the words
"double insulation" or "double insulated". The symbol [] (square within a
square) may also be marked on the
appliance. Failure to have the unit repaired by Sears service personnel can
cause the double insulation construction to become ineffective and result in
serious injury.

_WARNING:
Be sure to read the
electrical safety information in the safety rules section of this manual before
you begin. If you do not understand
the electrical safety information do not
attempt to use your unit. Seek help
from someone that does understand
the information or call the customer assistance help line at 1-800-235-5878.
GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication.
The chain oiler provides lubrication to
the chain and guide bar. Be sure to fill
the bar oil tank before each cutting session. Lack of oil will quickly ruin the bar
and chain. Too little oil will cause overheating shown by smoke coming from
the chain and/or discoloration of the bar.
For maximum guide bar and chain life,
we recommend you use Craftsman
chain saw bar oil. If Craftsman bar oil is
not available, you may use a good
grade SAE 30 oil until you are able to
obtain Craftsman brand. Use a funnel to
fill the tank. Replace oil cap securely.
Check oil level after every 15 minutes of
operation. Oil level can be monitored by
viewing the oil level indicator (see illustration in KNOW YOUR CHAIN SAW
section).
STOPPING YOUR UNIT
Release the trigger switch.
• If motor does not stop, disconnect
the extension cord. Discontinue use
of unit until repaired by a Sears Service Center.
STARTING YOUR UNIT
1. Connect the saw to a power source
using the proper size extension cord
(see SELECT AN EXTENSION CORD
in the OPERATION section).
2. Grip both handles firmly.
3. Push and hold the trigger lock-out
button with your right hand thumb.
4. Squeeze and hold the trigger switch.
OPERATING TIPS
• Check chain tension before first use
and after 1 minute of operation. See
CHECK CHAIN TENSION in the SERVICE AND ADJUSTMENTS section.
• Cut wood only. Do not cut metal,
plastics, masonry, non-wood building
materials, etc.
• Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair parts as necessary.
• Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility of kickback.
• Practice cutting a few small logs using
the following steps. This will help you
get the '_feel" of using your saw before
you begin a major sawing operation.
• Squeeze trigger switch and allow
unit to reach full speed before cutting.
• Begin cutting with the saw frame
against the log.
• Keep the motor at full speed the
entire time you are cutting.
• Release the trigger switch as soon
as the cut is completed, allowing
the motor to stop.
• Keep the cord away from the cutting area. Position cord so it will not
be caught on branches and the like
during cutting.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop the saw before setting it down.
TREE
FELLING
TECHNIQUES
4_WARNING:
Check for broken or
dead branches which can fall while
cutting causing serious injury. Do not
cut near buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be able to see well, nor during bad
weather such as rain, snow, or strong
winds, etc. If the tree does make contact with any utility line, the utility company should be notified immediately.
• Carefully plan your sawing operation in
advance.
• Clear the work area. You need a clear
area all around the tree so you can
have secure footing.
• The chain saw operator should keep
on the uphill side of the terrain as the
tree is likely to roll or slide downhill after it is felled.

FELLING LARGE TREES
(6 inches in diameter or larger)
The notch method is used to fell large
trees. A notch is cut on the side of the
tree in the desired direction of fall. After
a felling cut is made on the opposite
side of tree, the tree will tend to fall in
the direction of the notch.
NOTE: If tree has large buttress roots,
remove them before making the notch.
If using saw to remove buttress roots,
keep saw chain from contacting
ground to prevent dulling of the chain.
NOTCH CUT AND FELLING TREE
• Make notch cut by cutting the top of
the notch first. Cut through 1/3 of the
diameter of the tree. Next complete
the notch by cutting the bottom. See
illustration. Once the notch is cut remove the wedge of wood from the
tree.
2"
t Felling cut here
I/
-_--'_[:'ln
Seco cJ \
e
• After removing the wood from the
notch, make the felling cut on the opposite side of the notch. This is done
by making a cut about two inches
higher than the center of the notch.
This will leave enough uncut wood
between the felling cut and the notch
to form a hinge. This hinge will help
prevent the tree from falling in the
wrong direction.

NOTE: Before felling cut is complete,
use wedges to open the cut if necessary to control the direction of fall. To
avoid kickback and chain damage, use
wood or plastic wedges, but never
steel or iron wedges.
• Be alert to signs that the tree is
ready to fall: cracking sounds, widening of the felling cut, or movement in
the upper branches.
• As tree starts to fall, stop saw, put it
down, and get away quickly on your
planned retreat path.
• DO NOT use your saw to cut down a
partially fallen tree. Be extremely cautious with partially fallen trees that may
be poorly supported. When a tree
doesn't fall completely, set saw aside
and pull down tree with a cable winch,
block and tackle, or tractor.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a
fallen tree to the desired log size.
_)_WARNING:
Do not stand on the
log being cut. Any portion can roll
causing loss of footing and control. Do
not stand downhill of the log being cut.

First cut on compression
If saw becomes
pinched or hung in a log, don't try to
force it out. You can lose control of the
saw resulting in injury and/or damage
to the saw. Stop the saw, drive a
wedge of plastic or wood into the cut
until the saw can be removed easily.
Restart the saw and carefully reenter
the cut. Do not use a metal wedge. Do
not attempt to restart your saw when it
is pinched or hung in a log.
Use a wedge to remove pinched saw.
Turn saw OFF and use a plastic or
wooden wedge to force cut open.

2nd Cut
Overcutting
begins on the top side of
the log with the bottom of the saw
against the log. When overcutting use
light downward pressure.
Overcutting

BUCKING WITHOUT A SUPPORT
• Overcut through 1/3 of the diameter
of the log.
• Roll the log over and finish with a
second overcut.
• Watch for logs with a compression
side to prevent the saw from pinching. See illustration above for cutting
logs with a compression side.
BUCKING USING A LOG OR
SUPPORT STAND
• Remember your first cut is always on
the compression side of the log.
(Refer to the illustration below for
your first and second cut)
• Your first cut should extend 1/3 of the
diameter of the log.
• Finish with your second cut.

Undercutting
Cut
_¢/1 st Cut
Undercutting involves cutting on the
underside of the log with top of saw
against the log. When undercutting use
light upward pressure. Hold saw firmly
and maintain control. The saw will tend
to push back toward you.

LIMBING
• Limb a tree only after it is cut down.
• Leave the larger limbs underneath
the felled tree to support the tree as
you work.
• Start at the base of the felled tree
and work toward the top, cutting
branches and limbs. Remove small
limbs with one cut.
• Keep the tree between you and the
chain.
• Remove larger branches with the
cutting techniques described in
BUCKING WITHOUT A SUPPORT.
• Always use an overcut to cut small
and freely hanging limbs. Undercutting could cause limbs to fall and
pinch the saw.
PRUNING
LIMBING AND PRUNING
z't
_
A_,WARNING:
Be alert for and
guard against kickback.
Do not allow
the moving chain to contact any other
branches or objects at the nose of the
guide bar when limbing or pruning. Allowing such contact can result in serious injury.
_,WARNING:
Never climb into a
tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which can cause you to lose
your balance or control of the saw.
IMPORTANT POINTS
• Watch out for spring poles. Spring
poles are small size limbs which can
whip toward you or pull you off balance. Use extreme caution when
cutting small size limbs.
• Be alert for spring back from any
branches that are bent or under
pressure. Avoid being struck by the
branch or the saw when the tension
in the wood fibers is released.
• Frequently clear branches out of the
way to avoid tripping over them.
_,WARNING:
Limit pruning to limbs
shoulder height or below. Do not cut if
branches are higher than your shoulder. Get a professional to do the job.
• Make your first cut 1/3 of the way
through the bottom of the limb. This
cut will make the limb sag so that it
falls easily on the second cut.
• Next make a second cut all the way
through the limb.
• Finish the pruning operation by using
an overcut so that the stump of the
limb protrudes 1 to 2 inches (3-5 cm)
from the trunk of the tree.

GENERAL RECOMMENDATIONS
The warranty on this unit does not cover items that have been subjected to
operator abuse or negligence. To receive full value from the warranty, the
operator must maintain unit as
instructed in this manual. Various adjustments will need to be made periodically to properly maintain your unit.
Improper maintenance may cause
damage to the unit and possible injury
to the operator or bystanders.
CHECK FOR DAMAGED OR
WORN PARTS
Contact Sears Service Center for replacement of worn or damaged parts.
CHECK
CHAIN TENSION
_, WARNING:
Wear protective
gloves when handling chain. The
chain is sharp and can cut you even
when it is not moving.
Chain tension is very important. Chain
stretches during use. This is especially
true during the first few times you use
your saw. Always check chain tension
each time you use your saw.
1. Unplug unit from the power source.
2. Use a screwdriver to move chain
around guide bar to ensure kinks
do not exist. The chain should rotate freely.
NOTE: It is normal for a small amount
of oil to appear under the saw after
motor stops. Do not confuse this with a
leaking oil tank.
• Trigger Switch - Ensure the trigger
switch functions properly by squeezing and holding the trigger switch.
Make sure motor starts and stops.
• Oil Tank - Discontinue use of chain
saw if oil tank shows signs of damage or leaks.
• Power Cord - Discontinue use if
chain saw power cord shows signs
of damage or wear.
